The internet is a wonderful source of information but the problem with it is that incorrect information can be spread as easily as the correct stuff. My work on writing the new book on Bessler is proceeding well and I have tried to ensure that all the information in it is correct, however in the course of double-checking everything some inaccuracies are inevitably found.
In my first version of Bessler's biography I wrote during my research, I had come across no less than three accounts written over a period of some fifty years or more, which all use the same argument in support of their author's contention that Orffyreus was a fraud. They explain away Professor 'sGravesande's belief in the wheel in the following manner. I will quote from the latest account which uses very similar words to the two previous ones. Arthur W.J.G. Ord-Hume's book is called "Perpetual Motion - The History of an Obsession". After describing the examination of the wheel at Kassel by 'sGravesande, the author remarks;
'The Professor certainly seems to have had some measure of faith in the wheel and the demonstration of its ability to turn without apparent external force. We ought not to forget, though, that it may have proved easy to dupe an honest old man whose confidence in humanity was probably unbounded . . . .It is not recorded whether the aging academician ever received a reply to his letter to Sir Isaac Newton.'
As this argument attempted to cast doubt on the professor's competence to decide whether the machine was valid or not, it was important to check his age. If he was elderly, then his capacity as a valuable witness was potentially impaired. In fact, this 'honest old man', this 'aging academician' was born on the 26th September 1688, which means that at the time of the Kassel examination he had reached the grand old age of thirty-three! He lived for over another twenty years, dying in 1742. In 1730 he was described as one of the great luminaries of scientific experimentation at Leiden University, possibly the foremost University of the age. His lectures drew the biggest crowds of students. This does not sound like a man of failing intellectual powers, and he was certainly one who could form an opinion based on the evidence in front of him, which others could rely on as accurate. He would not have upset Orffyreus so much if he had not had the courage to ask the most searching questions concerning the Kassel wheel. The argument that he was old and gullible is invalidated.
It has also been pointed out that I did not include anything about Frank Edwards, "Bessler's Wonderful Wheel", 1956, in which he gives an account of Bessler's wheel. I omitted it because it contains information which is just plain wrong. One could kindly call it Poetic Licence, but it is misleading. According to Edwards, "When the oiled cloth was stripped away, said Count Karl, he found himself gazing upon a very simple arrangement of weights and levers. Orffyreus explained that he had conceived a system whereby the weights one side of the wheel were farther from the axle than the weights on the other side of the wheel, creating an imbalance which caused the wheel to move. The secret, if there was a secret, lay in the ingenious manner in which the weights on the ascending side of the wheel were prevented from following their normal path next to the rim. Count Karl said that these weights were blocked by small pegs which swung back out of the way as the weight passed the zenith." There is no documentary evidence to support this account and anyway it does not fit with Karl's recorded actions - it is wrong and that is why I originally left it out, however have included it in the new book if only to correct the information being published. Edwards includes a numerous other mistakes such as Christian Wagner being called Claus Wagner for example
But there are still factual errors being posted on the interner and copied and pasted on other websites. For example in the Gera certificate one of the signees is called Christian Lange and on one website it states that he was Bessler's cousin. This is not true, Bessler's cousin was Detter Langer, but obviously this was due to a simple misreading of the text, but it has been copied to two other web sites to my certain knowledge. In addition this same website has stated that another signee, Johann Georg Pertsch is described as a professor at University of Helmstedt, however he didn't graduate until 1716 and was only 18 in 1712. The correct man was his father of the same name and was never a professor and he did not attend University of Helmstedt. An easy mistake to make but it could lead to confusion.
There are numerous errors on the internet and I have tried to right those relating to Bessler and I hope that when my new book does finally appear it will be error free. But these little mischiefs do creep in and along with typos and spelling mistakes, are the author's bĂȘte noire.
My granddaughter wants me to include this clever little trinket,
"Don't let 'assume' make an 'ass' out of 'u' and 'me'".
